Abstract
Description
Technical Field
[0001] This utility model relates to a synthetic leather impregnation device, specifically a microfiber synthetic leather impregnation device, belonging to the field of synthetic leather processing technology. Background Technology
[0002] Microfiber synthetic leather is a type of synthetic leather. Because the base fabric is made of microfiber, the resulting synthetic leather has good elasticity, high strength, soft feel, and good breathability. It possesses many of the physical properties of high-end synthetic leather, and its outer surface also has the characteristics of natural leather. Synthetic leather requires impregnation treatment during the production process, mainly to give the base fabric specific physical properties and appearance, making it closer to the characteristics of natural leather.
[0003] However, when using an impregnation chamber to impregnate the base fabric, resin is a common impregnation solution. When existing base fabrics are impregnated by a resin impregnation machine, they mostly need to be soaked for a long time. The impregnation time is long, and the resin cannot quickly penetrate into the surface of the synthetic leather. The impregnation rate is slow, and the resin viscosity increases with the standing time, resulting in poor permeability during impregnation and uneven wrapping of the base fabric fibers. Surface defects appear during subsequent solidification or drying. Utility Model Content
[0004] The purpose of this invention is to provide a microfiber synthetic leather impregnation device to solve the above-mentioned problems. It can drive the slide bar to slide in the fixed seat, thereby driving the stretching roller to slide downward to stretch the base fabric. Therefore, it can make the base fabric better absorb the resin. It can also stir the impregnation tank to prevent the resin viscosity from increasing with the standing time, which would lead to poor permeability during impregnation, uneven fiber wrapping of the base fabric, and surface defects during subsequent solidification or drying.
[0005] This utility model achieves the above-mentioned objectives through the following technical solution: a microfiber synthetic leather impregnation device, comprising an impregnation box, an impregnation structure mounted on the top of the impregnation box, the impregnation structure including guide wheels, multiple guide wheels rotatably connected to the top of the impregnation box, a fixed frame fixedly connected to the top of the impregnation box, multiple pressure rollers rotatably connected to the fixed frame, a stretching structure installed inside the impregnation box, the stretching structure including a fixed seat, fixed seats fixedly connected to both sides inside the impregnation box, a sliding rod slidably connected inside the fixed seat, a stretching roller rotatably connected to the bottom end of the sliding rod, a slider fixedly connected to the sliding rod, the slider and the fixed seat slidably connected, a first spring fixedly connected between the slider and the fixed seat, an abutting wheel rotatably connected to the top of the sliding rod, a rotating shaft rotatably connected to the fixed frame, an eccentric wheel fixedly connected to the rotating shaft, the abutting wheel and the eccentric wheel abutting against each other, a connecting plate fixedly connected to the sliding rod, a top rod detachably connected to the top of the connecting plate, and a fixed plate fixedly connected to the top of the top rod.
[0006] Preferably, multiple fixing plates are arranged in a parallel relationship, and multiple through holes are provided on the fixing plates.
[0007] Preferably, multiple guide wheels and multiple pressure wheels are arranged in a linear distribution.
[0008] Preferably, two extrusion rollers are rotatably connected to the right side of the impregnation tank, and a motor is installed on the side end of the impregnation tank. The output end of the motor is fixedly connected to the extrusion rollers below.
[0009] Preferably, gears are fixedly connected to the side ends of both extrusion rollers, and the two gears mesh with each other.
[0010] Preferably, a limiting structure is installed on the fixed base, the limiting structure includes a limiting seat, the top end of the connecting plate is fixedly connected to the limiting seat, and the top rod and the limiting seat are inserted into each other.
[0011] Preferably, a limiting block is fixedly connected to the bottom end of the top rod, and a sliding groove and a limiting slot are provided at the outer end of the limiting seat.
[0012] Preferably, the bottom end of the push rod is slidably connected to an abutment rod, the top end of the abutment rod is fixedly connected to a fixing block, the fixing block and the push rod are slidably connected, and a second spring is fixedly connected between the fixing block and the push rod.
[0013] Preferably, the motor is equipped with a transmission structure, which includes a first pulley. The first pulley is fixedly connected to both the output end of the motor and the rotating shaft, and the two first pulleys are driven by a first belt.
[0014] Preferably, a second pulley is fixedly connected to each of the two rotating shafts, and the two second pulleys are driven by a second belt.
[0015] The beneficial effects of this invention are as follows: When impregnation treatment of the base fabric is required, the base fabric is staggered and inserted between the guide roller and the stretching roller. The base fabric enters the impregnation tank after passing the leftmost guide roller, and then rotates again through the stretching roller to the guide roller at the top of the impregnation tank. Through the squeezing of the guide roller and the pressure roller, it undergoes multiple squeezing and impregnation processes, thus achieving better impregnation of the base fabric's interior. The rotating shaft rotates within the fixed frame, thereby driving the eccentric wheel to rotate. The eccentric wheel, in contact with the abutting wheel, drives the sliding rod to slide within the fixed seat, which in turn drives the stretching roller to slide downwards to stretch the base fabric. Therefore, this allows for better impregnation of the base fabric's interior. The resin is absorbed, and then the eccentric wheel continues to rotate. The first spring fixed on the slider can drive the slider and the slide rod to slide and reset, thus stopping the stretching of the base fabric. After the shaft rotates one revolution, the subsequent base fabric is stretched again, which can better stretch the base fabric. Moreover, when stretching the base fabric, the slide rod can drive the connecting plate to slide downward. Therefore, by repeatedly sliding up and down the multiple fixed plates fixed on the top rod, the impregnation tank can be stirred to prevent the resin viscosity from increasing with the standing time, which would lead to poor permeability during impregnation, uneven fiber wrapping of the base fabric, and surface defects during subsequent solidification or drying.

[0023] Please see Figures 1-5 As shown, the microfiber synthetic leather impregnation device includes an impregnation tank 1. An impregnation structure 2 is mounted on the top of the impregnation tank 1. The impregnation structure 2 includes guide wheels 201.

An abutting wheel 306 is rotatably connected to the top of the slide rod 302. A rotating shaft 307 is rotatably connected to the fixed frame 202. An eccentric wheel 308 is fixedly connected to the rotating shaft 307. The abutting wheel 306 and the eccentric wheel 308 abut against each other. A connecting plate 309 is fixedly connected to the slide rod 302. A top rod 310 is detachably connected to the top of the connecting plate 309. A fixed plate 311 is fixedly connected to the top of the top rod 310.
[0024] As a technical optimization of this utility model, multiple fixing plates 311 are arranged in parallel, and multiple through holes 312 are provided on the fixing plates 311. Thus, through the through holes 312 provided on the fixing plates 311, the resistance of the fixing plates 311 inside the impregnation tank 1 can be reduced when the fixing plates 311 slide up and down.
[0025] As a technical optimization of this utility model, multiple guide wheels 201 are arranged in a linear distribution relationship, and multiple pressure wheels 203 are arranged in a linear distribution relationship, so that the base fabric can be impregnated multiple times.
[0026] As a technical optimization of this utility model, two extrusion rollers 204 are rotatably connected to the right side of the impregnation tank 1. A motor 205 is installed on the side end of the impregnation tank 1. The output end of the motor 205 is fixedly connected to the extrusion rollers 204 below. Gears 206 are fixedly connected to the side ends of the two extrusion rollers 204. The two gears 206 mesh with each other. Through the meshing of the two gears 206, the two extrusion rollers 204 are driven to rotate in opposite directions, thereby extruding the impregnated base fabric.
[0027] As a technical optimization of this utility model, a limiting structure 4 is installed on the fixed base 301. The limiting structure 4 includes a limiting seat 401. The top end of the connecting plate 309 is fixedly connected to the limiting seat 401. The top rod 310 is inserted into the limiting seat 401. The bottom end of the top rod 310 is fixedly connected to the limiting block 402. The outer end of the limiting seat 401 is provided with a sliding groove 403 and a limiting slot 404, thereby enabling the top rod 310 to be limited and fixed.
[0028] As a technical optimization of this utility model, the bottom end of the top rod 310 is slidably connected to an abutment rod 405, the top end of the abutment rod 405 is fixedly connected to a fixing block 406, the fixing block 406 and the top rod 310 are slidably connected, and a second spring 407 is fixedly connected between the fixing block 406 and the top rod 310, so that the top rod 310 can be abutted and lifted.
[0029] As a technical optimization of this utility model, a transmission structure 5 is installed on the motor 205. The transmission structure 5 includes a first pulley 501. The output end of the motor 205 and the rotating shaft 307 are both fixedly connected to the first pulley 501. The two first pulleys 501 are driven by a first belt 502. The two rotating shafts 307 are both fixedly connected to a second pulley 503. The two second pulleys 503 are driven by a second belt 504. When the motor 205 starts, it can drive the rotating shaft 307 to rotate within the fixed frame 202 through the transmission of the first pulley 501 and the first belt 502 with the second pulleys 503 and the second belt 504.
[0030] In use, when the base fabric needs to be impregnated, the base fabric is staggered and inserted between the guide wheel 201 and the stretching roller 303. The base fabric enters the impregnation chamber 1 through the leftmost guide wheel 201, and then rotates again through the stretching roller 303 to the top guide wheel 201. Through the squeezing of the guide wheel 201 and the pressure roller 203, the base fabric is repeatedly squeezed and impregnated, thus achieving better impregnation of the interior. The motor 205 is started, and the meshing of two gears 206 drives the two squeezing rollers 204 to rotate in opposite directions, thereby squeezing the impregnated base fabric. Simultaneously, the first belt pulley... The transmission between belt 501 and the first belt 502, the second pulley 503, and the second belt 504 drives the rotating shaft 307 to rotate within the fixed frame 202. This, in turn, drives the eccentric wheel 308 to rotate. Through the contact between the eccentric wheel 308 and the abutting wheel 306, the sliding rod 302 slides within the fixed seat 301, thereby causing the stretching roller 303 to slide downwards to stretch the base fabric. This allows for better resin absorption within the base fabric. Then, as the eccentric wheel 308 continues to rotate, the first spring 305, fixed to the slider 304, causes the slider 304 and the sliding rod 302 to slide back to their original positions, thus stopping the stretching of the base fabric. After the rotating shaft 307 rotates one revolution, the subsequent base fabric continues to be stretched, thus achieving better stretching treatment of the base fabric. During the stretching of the base fabric, the sliding rod 302 slides, causing the connecting plate 309 to slide downwards. Therefore, by repeatedly sliding up and down the multiple fixing plates 311 fixed to the top rod 310, the interior of the impregnation tank 1 can be stirred, preventing the resin viscosity from increasing with the standing time, which would lead to poor permeability during impregnation, uneven fiber wrapping in the base fabric, and surface defects during subsequent solidification or drying. The through holes 312 on the fixing plates 311 reduce the impact of the fixing plates 311 during impregnation. The resistance inside box 1 is such that when the fixing plate 311 needs to be installed, the push rod 310 is inserted into the limiting seat 401 and the limiting block 402 is inserted into the sliding groove 403. After the abutting rod 405 and the connecting plate 309 abut, the push rod 310 is pressed down. After the push rod 310 and the connecting plate 309 abut, the push rod 310 is rotated until the limiting block 402 slides into the limiting groove 404. Through the elastic force of the second spring 407 fixed on the fixing block 406, the push rod 310 can be driven to slide, thus driving the limiting block 402 to slide in the limiting groove 404, thereby limiting the limiting block 402, and thus enabling the push rod 310 to be installed.
